The tangle sent both riders barrelling off the circuit – and in Tamburini's case into the barrier - while Lascorz's bike would catch fire in the impact. The race was immediately stopped while Lascorz and Tamburini were taken to the medical centre, where it has been confirmed Lascorz is suffering from concussion and Tamburini has a broken collarbone.
Behind Laverty and Sofuoglu, Rea completed a magnificent run to third position on home soil, the 20-year-old recording his first WSS podium for Intermoto Honda in the process and cementing his status as a future British racing star.
He was comfortably ahead of Chaz Davies, the Triumph man making it a strong race for the local riders as he crossed the line in fourth place having overhauled Robbin Harms late on.
A strong race for a number of riders, Miguel Praia lowered his WSS best with a run to sixth on the second Parkalgar Honda, ahead of Matthieu Lagrive, David Salom and Massimo Roccoli.
Of the wild-card riders, British Supersport leader Sam Lowes crept into the top ten in tenth for GNS Honda, while James Westmoreland was 11th and Billy McConnell 13th. Alex Lowes, who had qualified as the best of the guest contingent, came off his Yamaha shortly after the start.
